ABSTRACT:
To solve degradation with time of a light emitting element by a new method. When the potential of an electrode of a monitor pixel is sampled and fed back to a light emitting pixel, degradation with time of a light emitting element can be corrected. In addition, when a writing period is divided into a plurality of periods during which a plurality of rows are selected, a gray scale can be expressed by a weighted light emitting period. That is to say, a light emitting device of the invention has a plurality of monitoring light emitting elements, a monitor line for monitoring changes in the potentials of electrodes of the plurality of light emitting elements, and a means for preventing, when any one of the plurality of monitoring light emitting elements is short-circuited, a current from flowing to the short-circuited monitoring light emitting element through the monitor line.
